Just installed a big bore 106 and 551 easy start cams on my 08streetglide. Have been in talks with thundermax. There was a map #337 bike did not like it at all they sent me a mod map. Seems to be better. My problem is on cold start up. If I leave the bike over night it is very hard to start. Tried adjusting cranking fuel but have had no luck. Does any one out there have any other ideas? Very frustrating

 

Never ran into that problem with mine, but you should do a data logging run and send it to them to diagnose. It can't hurt and they just might see something.

 

How old is your battery?

 

Good point. The TMax is very finicky when it comes to low voltage.
